What is agility?

Agility refers to the ability to change the body's position efficiently and to move quickly and easily in multiple directions. This involves the coordination of speed and balance, allowing an individual to start, stop, and shift directions promptly in response to dynamic movements or stimuli. Athletes often use agility during sports and activities that require quick changes in pace or direction, making it a crucial skill for performance in various physical activities and sports.

The other choices highlight different aspects of physical fitness. Lifting heavy weights pertains to strength training, running long distances is related to endurance, and performing exercises slowly and steadily emphasizes control and stability rather than quick movement. Each of these skills is important for overall fitness but does not encapsulate the essence of agility like the ability to change speed and direction does.
